imp module is deprecated

  /home/shougo/.local/lib/python3.9/site-packages/pynvim/compat.py:5: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation
for alternative uses
    from imp import find_module as original_find_module

I think importlib is better.

Would a pull request be of interest to the pynvim team?

[Shougo]

The PR is not easy. Because, importlib is not the same function.

This is now removed from Python 3.12, so pynvim is currently broken for the upcoming Fedora 39 (that will be released this fall circa October-November)

https://bugzilla.redhat.com/show_bug.cgi?id=2220350

is there any blocker to merging #461 - just the loss of Python 2.x compatibility?

[michel-slm]

@justinmk looks like there's some more call sites that are not fixed by #461

  File "/builddir/build/BUILDROOT/python-neovim-0.4.3-10.fc39.x86_64/usr/lib/python3.12/site-packages/p
ynvim/compat.py", line 5, in <module>
    from imp import find_module as original_find_module
ModuleNotFoundError: No module named 'imp'

I'll see if I can get those addressed

[justinmk]

@michel-slm thank you! If you find the time to do that I'll find the time to publish a release here, and revive the CI :)

@justinmk the commit you rebased from @Shougo is similar to what I had (but I was trying to get it to apply to 0.4.3 so it looked slightly different). I just switched to using the latest Git master, and on Fedora 38 (Python 3.11) I get an assertion error while on Fedora 39 (Python 3.12) I get more serious errors involving the event loop. Let me file two separate issues for those and we can continue this there.

@justinmk let's continue this in #528
